Sediment particles become smoother and rounder over time primarily due to abrasion and weathering processes. As these particles are transported by water, wind, or ice, they collide with each other and with other surfaces, leading to the gradual removal of sharp edges and corners. Chemical weathering can also contribute by dissolving minerals and altering the particle's surface. Over time, these processes result in the characteristic shape of well-rounded sediments.
Sediments eroded by water in a stream become smoother and rounder through a process called abrasion. As the sediments are transported by the flowing water, they collide with each other and with the streambed, causing their edges to wear away. This constant friction gradually reduces sharp edges and corners, resulting in more rounded and polished shapes. Over time, the continuous movement of water further enhances this smoothing effect, leading to the characteristic rounded appearance of river rocks.
The loss of edges on sediment grains best describes the process of sediment abrasion or weathering, where particles collide and rub against one another, leading to the rounding of their edges. This process typically occurs in environments with high energy, such as rivers or beaches, where sediment is continuously transported and reworked. As a result, grains become smoother and more rounded over time, reflecting their transport history and the conditions of their depositional environment.
Igneous rock becomes sediment due to exposure to chemical and mechanical weathering at or near the surface.

Sediment becomes compacted through the pressure of overlying layers of sediment, water, and other materials. The weight from these layers squeezes the sediment particles together, forcing out the spaces between them. Over time, this compaction can lead to the formation of sedimentary rock.

When they are ready! Women's breast continue to grow until the end of their teenage years so you breast buds will eventually become rounder!
Mountains can become rounder over time due to erosion processes such as weathering, abrasion, and mass wasting caused by wind, water, and ice. These processes gradually wear down the sharp edges and peaks of mountains, leading to a smoother, more rounded appearance over time.
It can cause ears to become rounder. In rare cases they can also become darker.

Yes.
The bedload becomes smaller when the river is flowing downstream, and the rocks also become smaller, smoother and rounder due to attrition and abrasion. (The reason the flow slows down is because the energy of the flow decreases.)
The overall process is called Solifluction. If you imagine single particle (in the soil) on a gentle slope. When the water in the soil freezes, it expands and forces the particle away from the slope at right angles to the slope. When the ice then thaws gravity will cause the particle to settle back but the movement will be in a downwards direction, not in the direction it first moved. Add this movement together, repeate season after season and the particle gradually moves down slope.
when particles collide with each other and with other object in their path it happens when sediments is transported from its source to where it is deposited. these collision can cause the particles to change size and shape. angular and uneven rocks are when particles that have moved long distances from the source tends to be more rounder and smoother. the farther sediments travel from its source the finer and smoother the particles of sediments become.
The greater the time that stream sediment is transported, the greater the probability that the sediment will become more rounded and well-rounded due to abrasion and attrition processes.
